2 Claims.

This invention relates to` an apparatus for coating or saturating material, and more particularly for coating or saturating siding, formed of fibre board such as Celotex orsimilar or other fibrous material, which is employed in connec-` `tlonwith the walls of buildings or other structures, with asphalt.

'I'he primary object of the invention is to provide an apparatus of this character which expeditiously and automatically coats or saturates the siding by flotation in the asphalt or` coating so as to thoroughly coat or saturate both faces and all edges thereof, and subsequently removes and dries same.

Further the invention aims to provide an apparatus of the character set forth, wherein after `coating the siding is drained of any surplus, and

is dried prior to removal from the apparatus. and also dried in the presence of heat derived from that applied to maintain the coating at a` predetermined consistency. .I

Also the invention aims to provide an appa- `ratus` having means for automatically "feeding the siding into the apparatus and for `removal saturation.

The invention has still further and other objects which will be later set forth and of themselves manifested in the course of the following description.

4In the drawings:

Fig. 1 is a side elevation, partly in section;

.and

Fig. 2 is a section on line 2-2 of Fig. 1.

In proceeding in accordance with the invention a tank I, is employed, which is supplied with a quantity of liquid asphalt to constantly maintain a sumcient depth in order to enect complete and thorough coating or saturation oi' the siding. Heating pipes I' are disposed in the bottom of the tank to maintain the asphalt in liquid state or of such consistency to assure requires aminimum of time in coating, while 4 still eecting complete or thorough coating or complete coating orV saturation. These pipes are supplied with heat from any suitable source so as to maintain the asphaltat the desired or predetermined consistency. A main shaft 2,` is journalel in the tank by means` of bearings 'l and has a series of disks 4A, rigidly secured thereto. Circular series of radial fingers or arms l. are rigidlysecured to the disks onthe opposite side faces thereof and project radially therefrom. `Adjacent of the arms 5 `are radially spaced to form pockets in which. the siding is received. s

A large gear 6, is keyed to the shaft 2,'and is in mesh with a small gear 1 that is keyed on'a second shaft 8 journaled in bearings 9, which latter are suitably, supported in the tank. A second gear i0 is also keyed on the shaft 8, and is in mesh with a pinion Il, `keyed to a` stub shaft I2; the `latter further having a `gear I3 keyed thereto which meshes with a pinion i4 von a driveshaft l5,` the shaft -I5 also carrying sprockets I 5'. l f

Horizontal endless chains I6, are trained over the sprockets I 5', and over` sprockets I1, the sprockets l5' being located within the tank and the sprockets I'lv withoutthe tank, the'chains passing through an opening I1' in the adjacent end wall of the tank. The chains are provided with abutments I8 to engage ,the siding S, that is stacked in the hopper I9. The bottom of the hopper is open, so that the upper flights of the chains I6 can move therethrough, and have their abutments I8 engage the foremost edges of the siding thus moving same through the opening l1' and into the pockets between adjacent fingers 5.

The conveyor which removes the coated and dried siding is composed of a pair of endless chains 20 trained over sprockets 2| and 22 and which move through an opening 23 in the -adjacent end wahl of the tank. 'I'hese chains likewise have abutments 24 to engage the siding and remove same from the rotary carrier.

The conveyor chains 20, are driven by means of endless'chains 25, which are trained -over sprockets 26, and over sprockets corresponding to and located rearwardly of sprockets 22, on shaft 22'. Intermeshed gears 2B' shown in dotted lines in Fig. 1, are connected to shaft 2l' that carries sprocket 26 and to shaft il" to drive shaft 25 from shaft i1".

of the horizontal conveyor are driven from sprockets I5' on shaft i5. A preferably stationary conveyor 21 receives the coated and dried The chains il" I1" on which the sprockets I'I are mounted and shaft 25. The lower ends of the parts 219, are

supported by braces 30 that are secured to thel tank. Stiffening plates or gussets 3| within the tank are preferably provided for the arms; 28.

In operation the .shingles are stacked in the hopper I9, and are individually fed therefrom Vin timed relation into the pockets between the radial fingers 5, of the rotary carrier, the latter moving in a clockwise direction. Rotation of the carrier causes the material to be moved into the coating bath where it is thoroughly saturated and coated by the asphalt, and by flotation remain in the pockets of the carrier, during the continued rotation of the latter.

As the siding or boards reach the bath it will be observed that same are rotated through the coating at 160 and then through the free space above the level of the bath, whereby the surplus coatingr is drained from the material and the latter dried, the drying being enhanced by the presence of the heat from the pipes I', which in turn maintains the bath heated to a predetermined degree.

When the siding or boards in the successive pocketsreach the removing conveyor 20, it will be seen that they will be engaged at their inner ends by the abutments 24 in timed relation and removed on tothe conveyor 21.

The gearing between the rotary carrier and the drive shaft I5, is illustrated by way of example, and it will be understood that any type of'reduetiongearing may be employed so that the speed of travel of the rotary gearing may be 'less than that of the movement of the conveyor 20, the gearing being timed so that as the pockets of the rotary carrier successively reach the upper flight of the feeding conveyor I6, a siding will be deposited in the pocket. Likewise the movement of the removing conveyor chain 20 is such that as each successive pocket reaches the upper illght thereof same will be removed by the conveyor.

It will be also understood that the invention is susceptible to such changes, alterations or modications as may fall Within the scope of the appended claims.

I claim:

y 1. An apparatus of the type set forth including a tank having an inlet and an exit formed toreceive a coating solution, means to maintain the solution in a heated state, a rotary material `carrier mounted in the tank and having radial means provided with open outer portions for receiving and conveying the material through the solution, the travel of the upper arc of said carrier occurring above the level of the solution in the tank, whereby after the material has been coated to move the latter through the space above and over the solution level thereby to drain surplus of the solution oi the material and to dry the latter as the material approaches the exit, means to feed the material to the carrier including an endless chain extending through the inlet and means to remove the material from the carrier and through the exit upon the material reaching the exit including an endless chain operating through the exit of the tank.

2. An apparatus of the type set forth including a tank for containing a coating solution, a rotary material carrier mounted in the tank provided with radially disposed'spaced arms having open outer portions for receiving, and conveying the material through the solution thereby to coat same, means for radially feeding the material to the carrier, and other means for removing the material from the carrier having a portion thereof projecting into the space between the arms, said material removing means embodying an inclined endless chain having means to engage the inner ends of the material.
